Here is the full text of President Obama’s May 23 speech on national security, as prepared for delivery today. The President was interrupted by Medea Benjamin of Code Pink, who challenged him on the urgency of closing Guantanamo Bay prison. He then spoke off script, allowing his heckler to speak at length, and he responded to her statements. A footnote: Ms. Benjamin, whom the President addressed as “that young lady interrupting me,” is 60 years old.
